Ensures consistent brand and technical terminology across language pairs using CSV-importable shared glossaries, automated glossary generation, shared style rule lists, and translation memory.
Enhances original drafts and translated copy with real-time sentence rewrites, word alternatives, and one-click tone adjustments (e.g., Business, Academic, Casual, Diplomatic) via browser, desktop, and Microsoft 365/Google Workspace add-ins.
Provides real-time spoken language translation and live multilingual captions for video conferences and mobile in-person dialogues, with 30 minutes per user per month included in paid DeepL Pro plans.

Detect and reduce AI-generated traces in academic papers across CNKI, VIP and other Chinese platforms
Run checks modelled on CNKI, VIP, Gezida, Daya, Wanfang and an overseas detector to see how AI-generated your text looks before you submit it.
Dedicated rewriting optimises passages so they carry fewer traces of machine generation, with the vendor reporting typical results under 10% on the simulated platforms.
A separate rewriting mode targets similarity against published literature, offering varied phrasings while keeping the original meaning intact.
Document-wide processing that rewrites the whole paper at once rather than forcing you to edit paragraph by paragraph.
